The daylily is practically disease- and pest-free, easy to grow, and resilient to drought, shade, and poor soil, making it the ideal perennial. Discover how to cultivate daylilies and quickly propagate them for extra plants!
These plants, which are originally from Asia, have adapted so successfully that many of us consider them to be locals. Imagine how thrilling it would have been for a 16th-century traveller to tour the Orient and discover these beautiful flora! Daylilies were welcomed into European gardens by gardeners, and they traveled to the New World with the first colonists.
Daylilies have a long tradition of being used in both gardens and kitchens. The delicate foliage was used as a spring green, the buds and blooms were added to soups and consumed raw, and the swollen parts of the root were cooked and consumed. When cooked in stews, soups, or sauces, all sections have a mild peppery flavor and serve as a thickening factor.
Considering that each blossom only lasts for one day, their botanical name Hemerocallis means “beauty for a day.” Daylilies grow from fleshy roots instead of genuine lilies’ bulbs, and their flowers appear on scapes that are leafless and rise above the leaves. One of the 12–15 buds on each scape opens every two days. With 4 to 6 scapes on an adult plant, there is a lengthy bloom time. Some plants can grow up to six feet tall, measured by the length of the scape!
Divide the daylily clumps before the autumnal equinox in late summer or early fall after flowering (late July to mid-September) in order to multiply them. Before winter, the plants need at least six weeks to reestablish themselves.
Even though many gardening guides advise using two garden forks to cut or push the roots apart, I’ve had good luck by briefly soaking the roots in a pail of water until the majority of the soil is gone. After that, breaking up the clumps is considerably simpler (and you do not damage the plant). Dig up the whole cluster. Check the location of the crown once the earth has been removed. Break it up into larger clumps beginning at the edge (two, three, or no more than four). Reduce the length of the leaves by about a third to a half. Replant. If you want to hasten growth, you can add a fertilizer heavy in phosphorus.
Daylilies thrive in full sun and a location with healthy, well-drained soil, though they will endure in less-than-ideal situations. One inch should be buried beneath the plant’s crown, which is where the leaves and roots converge. Water and mulch a daylily that has just been planted to keep it moist. Daylilies are unaffected by the red lily-leaf insect, which has ravaged Asiatic and Oriental lilies.
There are countless lovely daylilies to pick from. To have daylilies bloom from late spring into fall, combine early, mid-season, late flowering kinds, and repeat bloomers.
Did you know: Despite their name, daylilies are not “real” lilies (from the genus Lilium). If you’re interested in learning how to grow Asiatic and Oriental lilies, visit our Lilies page.
How do you encourage daylilies to grow?
- Cut the entire flower stem, or “scape,” off of your daylilies to encourage more blooms and stop the development of seeds. Allowing daylily seeds to self-sow will result in a variety of flowers (and probably fewer blooms) the next year because daylily seeds do not produce the same variety as the hybrid parent plant.
- Cut back your daylily foliage to a height of around 1 foot if it appears straggly in the sweltering summer heat. This will stimulate new leaves to grow.
- In the late fall or early spring, remove all dead foliage.
- Although daylilies are fairly effective in crowding out weeds, get rid of any that emerge.
When and how are daylilies split?
Your daylilies will remain content and uncrowded if you divide them for root division propagation. Generally speaking, daylily plants require division every three to five years. You must dig up the plants, separate them into portions, and then replant them to divide daylilies. Your daylilies can be divided into multiple plantings, given away, or stretched out.
When should daylilies be divided? The plants need a few years between divisions so they can grow new roots. Daylilies can be divided after two years in the ground, although it is better to do so every three to five years. Early spring, before the plants start to grow, or late fall, after the blooming season, are the ideal times to divide daylilies.
Daylilies are rather simple to divide. A sharp splitting tool or pair of scissors, as well as a shovel or spade, are required. Do the following to divide daylilies:
- Dig up the entire root system of your daylily plants.
- Shake or brush away the dirt from the roots gently.
- Sort the roots into at least two separate groups. Each group needs a good number of roots and at least three stems.
- Discard any broken or unhealthy roots after cutting the roots apart.
- Plant new daylilies. Set the crown at ground level and take advantage of the chance to add some new compost to your growing area.
That’s all, then! Your “new daylilies” should continue to flourish and add even more color to your garden than the original plants did.
What should you do with daylily seed pods?
the gathering of daylily seeds Allow the seed pod to dry naturally on the stalk if the blossom turns into a seed pod. Pick it when it begins to turn brown and crack open, and keep it in a warm, dry area until you’re ready to plant. The seed might be planted right away.
On a daylily, where are the seed pods located?
Day lilies (Hemerocallis spp.) are adaptable and eye-catching flowers that, depending on the species and cultivar, grow as perennials in sunny or moderately shaded garden beds in U.S. Department of Agriculture plant hardiness zones 3 to 9. The blooms bloom in the spring and continue into the summer, maturing into pods that contain shiny, black seeds that can be used to start new plants. Despite their nondescript appearance, daylily seed pods can be easily distinguished once the fundamental characteristics are understood.
Tip
A daylily plant’s seed pod is an oblong capsule situated atop the flower scapes that is separated into pieces that separate when the seeds ripen. Fertilized blossoms produce green seed pods, which turn brown as the seeds ripen.
Should daylily seed pods be removed?
Daylilies are a plant that both amateur and expert gardeners can enjoy. They take very little extra care and thrive in practically any sunny environment, whether it has sandy soil with good drainage or rich, moist soil. Many varieties are hardy to Zone 3 and will thrive with very little additional irrigation or fertilizer. Daylilies also come in a broad range of hues, including white, pink, red, purple, yellow, and orange, as well as any imaginable combination of each. These colors blend in with practically any landscape. The absence of pest and disease issues is perhaps the best feature. Deer may cause problems when they devour sensitive flower buds and early spring foliage.
Daylilies will bloom from May until late September, depending on the cultivar. A variety of daylilies with various blooming periods can be planted together to produce flowers for almost the entire growing season. Although daylilies’ petals only last a day, as their name suggests, vigorous plants can produce blossoms for several weeks.
Aesthetic considerations play a role in the decision of whether or not to deadhead daylilies. Daylily flowers that have been used up seem rather ugly. They quickly turn to mush when they fade, occasionally drying onto immature buds and preventing them from fully opening. Successfully pollinated flowers develop seed pods. The majority of flowering plants, including daylilies, put a lot of energy into making seeds. Future blooming potential and root and shoot growth are also negatively impacted by seed output. In order for daylilies to produce more flowers the next season, seed pods should be removed for the sake of the health of the plant.
Although it takes time, deadheading daylilies is not difficult. Feel free to skip the daily deadheading of your daylilies. It should be sufficient to deadhead plants at least a few times during their bloom period to prevent them from focusing their energy on creating ripe seed. When a plant has fully bloomed, all you have to do is use your fingers to snap off the spent flower heads and seed pods. Flower stalks can be pruned with hand pruners to the base once the blooms have faded.
Can daylily seeds be saved?
It can be exciting to save and store daylily seeds from your favorite daylily cross, but seeing the flower buds gradually emerge is even more satisfying. You can grow an entirely new variety of daylily by storing the seeds. By manually pollinating the desired daylily blossoms and crossing two flowers, you can create your own seed strains. The long single pistol has the stigma at the very end. It protrudes from the daylily flower’s throat and rests amidst the stamen cluster. If the crossings are successful, the pollen only needs 30 minutes to travel along the pollen tube and begin developing a seedpod. But for this to work, the appropriate daylily varieties must have been crossed. Once you’ve combined the appropriate flowers, you can use a little drawstring nylon mesh bag to cover the flower where you’ve applied the pollen to the stigma. This accomplishes two goals.
- to prevent other pollinators, such as bees and insects, from visiting the newly hybridized flowers.
- You won’t lose any seeds if you neglect to collect them.
From pollination to seed preservation, it only takes 6 to 8 weeks. Tetraploid daylilies must wait 6 weeks, whereas diploid daylilies must wait 8 weeks. It’s crucial to harvest and collect daylily seeds at the proper time. Daylily seed collection that is done too early can be disastrous.
Removing daylily seeds is a necessary part of daylily maintenance. When the seed pods are mature, ripe, and plump, this is done. At this point, the seed pod has turned brown and the seed case is beginning to separate. Only when the seeds are completely black and not cream or brown can you tell that the daylily seeds are ripe. At this time, you can begin collecting daylily seeds for storage and upcoming planting.
Only do this on a bright, sunny day after it hasn’t rained, and when the seedpod first begins to break open. Before the birds devour the seeds, carefully remove and store the black seeds. Depending on the size of the seed pod and the size of the bloom, the three-part seed capsule typically contains 1 to 20 seeds.
The seeds should not be kept in plastic bags because doing so would cause them to sweat and rot.
Before storing your seeds, make sure they are totally dry. To properly dry the seeds, you might need to spread them out on newspaper, brown paper, or paper towels for up to a week. Otherwise, simply place the seeds into their envelopes and prepare them for storage. If necessary, leave the envelopes open to allow the seeds to properly air dry and label the seed packages accordingly. The seed bundles should then be sealed for storage.
The ideal place to keep daylily seeds for future planting is in the crisper at cool temps in the refrigerator. This will keep the seeds fresh but prevent them from freezing.
